I don't know if they've changed or not, but at one time they called for
keyboards that slope downwards away from the user. The rational was
that the relaxed position of the wrist left the hand in that position.
Unfortunately that is fully extended and the natural rest position (not
hanging) is about half way between the full down and full up position.
I wonder how many problems they created with that one.
